FIELD OF THE INVENTION

The present invention relates to storage and charging systems for electronic devices. More specifically, the present invention relates to a system for centralized storage, charging, deployment, and inventorying of a plurality of portable electronic devices.

BACKGROUND

Portable electronic devices are generally known in the art. Portable electronic devices are quickly becoming common place in personal and professional endeavors, including educational and business settings. While use of portable electronic devices initially grew with individual use, organizations, including educational and business organizations, now will purchase a number of portable electronic devices for use by students, employees, or other users.

These purchasing organizations may desire a certain amount of control upon the portable electronic devices. The amount of control to assert may be dependent upon a number of factors considered by organizations, including, but not limited to, management of the portable electronic devices, inventory of the portable electronic devices, the type of user of portable electronic devices, the number of users for each portable electronic device, the environment in which the portable electronic device is in use, the relationship between the user and organization, the number of portable electronic devices in use, updating and maintenance of the portable electronic devices, and/or minimizing risk of loss and/or replacement costs of the portable electronic devices. Which factor(s) have the greatest weight dictating the necessary amount of control will be dependent upon the specific purchasing organization.

For example, in a school setting, a portable electronic device may be assigned to a specific student. That student may pick up the portable electronic device at a certain time during the school day, such as at the beginning of the school day, use it throughout the school day, and return the portable electronic device at the end of the school day. In another example, in a school setting, a classroom of students may use a number of portable electronic devices for a period of time during the day. As the students turn over in the classroom, such as by changing classes during the day, different students may use the number of portable electronic devices. As such, a plurality of different students may use a single portable electronic device during a day. In both of these examples, while utilizing the portable electronic devices as an educational tool is an outstanding way for students to learn, it can lead to issues in maintaining the portable electronic devices. For example, it may be difficult to inventory the devices during the day, charge or recharge the devices, account for the return of all devices once students complete use of the devices, and/or efficiently deploy new software or associated updates.

Similar to a school setting, portable electronic devices may be deployed for public use at libraries or other public access buildings. In this setting, the portable electronic devices may be checked out to users for a period of time. Again, many of the same problems as would arise in an educational setting, such as the ability to inventory or account for the return of all devices, may arise at these public settings.

As another example, businesses or hospitals/medical service providers may deploy portable electronic devices in association with business operations or providing medical services, respectively. In order for efficiency or operational gains to be realized by use of the portable electronic devices, the portable electronic devices must be operational and must be used. The inability of the business or medical service provider to control the portable electronic devices can interrupt any efficiency or operational gains. For example, should an employee take a portable electronic device from the premises and forget to return it, that employee will not be able to use the portable electronic device during performance of his or her job. Similarly, if an employee fails to charge or recharge the battery of the portable electronic device, the portable electronic device can run out of power during an employee's work day, rendering the portable electronic device useless. As another example, should an employee remove the portable electronic device from the premises, the information stored on the electronic device may be misappropriated. This and other situations not referenced can lead to inefficiencies and unnecessary risks of loss.

As another example, various service industries may deploy portable electronic devices in association with the performance of services. As an example, certain service providers may employ a plurality of employees whom are deployed off-site to perform their job. These employees may each require a portable electronic device in the performance of their job responsibilities. In addition, these employees may require daily travel in the performance of their job responsibilities. Again, many of the same problems as recited above, such as forgetting, misplacing, losing, or failing to fully recharge portable electronic devices, or the failure of employees to properly maintain the portable electronic devices, may lead to interruption of efficiency, loss of operational gains, and/or unnecessary risk of loss.

As another example, sports teams may deploy portable electronic devices in association with preparation of athletes for sporting activities. For example, local, college, and/or professional sports teams may employ portable electronic devices to communicate plays or other game planning materials for athletes. For example, a sports team, such as an American football team, may communicate a playbook on a portable electronic device assigned to each player. While the portable electronic devices provide the ability for the player to easily transport and use game preparation materials outside of athletic facilities, there are some disadvantages. For example, it can be difficult for the sports team to easily and efficiently update game planning materials. Again using the example of an American football team, a professional team typically has 53 active players divided between offense and defense. Game planning materials typically are updated on a weekly basis depending upon the opponent any given week. Accordingly, it can be difficult to quickly and efficiently distribute updated game preparation materials to the portable electronic devices assigned to each of the players. Further, the updating and distribution process becomes more onerous considering the minimum frequency of weekly update distribution.

Accordingly, what is needed is a system for centrally storing a number of portable electronic devices in a predetermined location. In addition, the system would allow for the batteries of the portable electronic devices to be charged and/or recharged. In addition, the system would provide a system for locking or protecting the portable electronic devices from misuse or theft. In addition, the system would provide a systematic fashion to facilitate storage, security, accountability, and instant inventory verification for the efficient management and use of the portable electronic devices. In addition, the system would provide for convenient and easy movement of the mobile tower assembly between locations for storage, for charging of loaded electronic devices and for self-dispensing and/or return of portable electronic devices by users at convenient user sites.

Referring back to FIGS. 4 and 5, first and second edge portions 132, 133 may have a tapered height as shown. As first and second edge portions 132, 133 extend away from back tabs 134, 135, the height of first and second edge portions 132, 133, as measured by a distance perpendicular to bottom portion 131, decreases. Stated otherwise, the edge of first and second edge portions 132, 133 furthest away from bottom portion 131 has a negative slope from an edge closest to back tabs 134, 135 to an edge furthest away from back tabs 134, 135. The decreasing slope or decreasing height creates sufficient open area to allow for a user to quickly and accurately identify, confirm, and/or inventory electronic devices stored in the storage bay of each shelf portion 130.

Referring to FIGS. 2 and 3, each of the plurality of shelf portions 130 may include one or more retaining tabs 136. Retaining tabs 136 may project away from bottom portion 131. In addition, retaining tabs 136 are preferably parallel to bottom portion 131. Each of the plurality of shelf portions 130 may also include one or more retaining hooks 137. A retaining hook 137 may be respectively coupled to first and second back tabs 134, 135. Retaining hooks 137 preferably project away from first and second back tabs 134, 135. Further, retaining hooks 137 are preferably parallel to bottom portion 131. Each retaining hook 137 may include a laterally projecting hook portion 137 a defining a shallow channel between the hook portion and the rear surface of the back tab 134 or 135 from which the hook projects. Each of the plurality of shelf portions 130 may also include one or more retaining apertures 138. A retaining aperture 138 may be provided in each of the first and second back tabs 134, 135. Retaining apertures 138 may be aligned with a corresponding shelf attachment member aperture 122 provided in first member 111 of tower support 110.

The plurality of shelf portions 130 may be removably attached or coupled to mounting support portion 110. The removability and/or additive nature of shelf portions 130 provides expandability for the addition or removal of one or more shelf portions 130. In addition, the location of shelf portions 130 may be customized based upon the heights of the users. For example, in end uses where users may be shorter, such as a primary school setting, shelf portions 130 may be provided at lower locations of tower support 110 to correspond for the relatively shorter heights of the users. Similarly, in end uses where users may be taller, such as a secondary school setting, shelf portions 130 may be provided at higher locations of tower support 110 to correspond for the relatively taller heights of the users.

Referring now to FIGS. 2 and 3, the retaining tabs 136 of each shelf portion 130 are removably received by a respective first shelf receiving slot 119 a provided in mounting support portion 110. Preferably, first shelf receiving slots 119 a are provided through first member 111. In addition, each retaining hook 137 of each shelf portion 130 is removably received by a respective second shelf receiving slot 119 b provided in mounting support portion 110. Preferably, second shelf receiving slots 119 b are also provided through first member 111. When each shelf portion 130 is engaged with first member 111, each retaining tab 136 is received by an associated first shelf receiving slot 119 a, while each retaining hook 137 is received by an associated second shelf receiving slot 119 b. In addition, the channel defined by the hook portion 137 a of each retaining hook 137 receives a portion of first member 111. More specifically, a portion of the hook 137 is received by second shelf receiving slot 119 b such that an end edge portion of the slot 119 b defined by the first member 111 is received within the channel defined by the hook portion 137 a of each retaining hook 137. To further facilitate engagement and retention of shelf portions 130 to mounting support portion 110, the first and second back tabs 134, 135 of each shelf portion 130 may have a bias. The bias preferably is in a direction to encourage the first member 111 to be received within the channel defined by the hook portion 137 a and engage each retaining hook 137 upon receipt of each retaining hook 137 by the associated second shelf receiving slot 119 b.

As best illustrated in FIGS. 2A and 2B, in an exemplary embodiment the first edge portion 132 is integrally formed with and at an approximately right angle to a first side of the bottom portion 131, while the back tab 134 is integrally formed with and at an approximately right angle to the first edge portion, such that the first edge portion 132 extends upwardly from a side of the bottom portion 131, and the back tab 134 extends from the back end of the first edge portion 132 generally parallel to the back edge of the bottom portion 131. The first edge portion 132 thus has a vertical bias which positions the retaining hook a fixed distance from the first side of the bottom portion 131. The second edge portion 133, back tab 135 and attached retaining hook 137 are likewise attached to the opposite second side of the bottom portion 131 and each other to likewise position the attached retaining hook a fixed distance from the second side of the bottom portion. The retaining hooks are thus seen to have a structural bias toward fixed spaced positions above the back edge of the bottom portion 131. To facilitate connection of a shelf portion 130 to the first member 111, it can be seen that the side edge portions 132 and 133 may be manually flexed toward each other to reduce the distance between the retaining hooks 137 and to permit the retaining hooks to be inserted into the second shelf retaining slots 119 b in the first member. The outer margins of the retaining slots 119 b are more closely spaced from each other than the distal margins of the hooks, so that when the manual flexing force on the edge portions 132 and 133 is released, the structural bias of the shelf portions will pull the retaining hooks apart and the end edge portions of the receiving slots 119 b will be received and engaged in the channels defined by the retaining hook portions 137 a to retain the shelf portion 130 on the first member 111. In an exemplary embodiment a support flange 139, best shown in FIG. 2B, may be unitarily formed with the shelf portion 130 and extend downwardly from the back edge of the bottom portion 131 a desired distance to provide additional support and resistance to downward bending of the retained shelf portion. In addition, shelf portions 130 may be coupled to mounting support portion 110 with a retaining member (not shown). A suitable retaining member may include, but is not limited to, a screw, bolt, pin, or any other suitable removable engagement member. A retaining member may be received by one or more retaining apertures 138, and the corresponding shelf attachment member aperture 122 aligned with each retaining aperture 138. While a particular advantageous engagement structure has been illustrated and described for mounting a shelf portion on the first member 111 such that any single shelf member may be attached to or detached from a mounting support assembly without interference with any other mounted shelf portion, it should be understood that any mechanical connection of shelf portions to support assembly is contemplated within the spirit of the invention.

FIGS. 22-31 a illustrate several alternative exemplary embodiments of improved storage management systems for electronic devices.

FIGS. 22-27 are photographs of an improved counter top assembly embodiment 501 of the improved storage management system for electronic devices. FIGS. 22 and 23 show front views of the embodiment having an improved shelf structure. The improved embodiment has a shelf 531 having a first edge portion 532, second edge portion 533, first back tab 534, second back tab 535, and bottom portion 531. At the front portion of various embodiments of the improved shelf 531, the bottom portion 531 has a first length that extends beyond the front end of the respective edge portions 532 and 533 at its angle of intersection with the edge portions. At the mid-portion between the first and second sides of the shelf structure, the bottom portion 531 has a second, shorter length that is approximately two-thirds of the length of the edge portions as measured from the back tabs 534 and 535 of the shelf. This length extends centrally for approximately half of the width of the bottom portion 531. Between the first length and second length, the shelf bottom portion length tapers rearwardly. The result is that the front margin of the base defines an approximately U-shaped cutout 531 a or open area from the front of the shelf. This U-shaped cutout is properly sized for a hand to be able to easily and simultaneously grip both the upper and lower surfaces of an electronic device to facilitate its easy insertion in and removal from the shelf 530 or the improved storage management system.

It should be understood that exemplary embodiments of the improved storage management system for electronic devices using the improved shelf structure may include shelves 530 of differing sizes but provided in connection with the same tower structure. The differing shelves may be provided to better accommodate varying sizes of devices. For example, a user may want to have a spot for a full-size laptop and for a tablet or other smaller device. In various embodiments, the user may select the sizes of shelves provided in the structure according to the user's various device-driven needs. As shown in FIGS. 22, 23 and 27 shelves 530 of any size may snap into the tower assembly channel support 570 through slots and retaining tab and retaining hook systems provided as described above with reference to FIGS. 2-7, or be connected by other suitable fastener means (not shown).

FIGS. 23, 25, 26, 30 and 31 also show accommodating structure for an improved cable management system. FIG. 25 shows that in various embodiments, the cable management system may include a vertical channel support 570 having a rear corner access panel 571 attached to the vertical tower support in spaced relation behind the front wall of the tower support access panel. The access panel 571 may be comprised of a rounded piece of metal having apertures. The apertures may have several functions including providing air circulation to the charging devices. The cable management access panel 571 may be removably coupled to the tower vertical channel support 570 in various ways, including snap-fit engagement of the respective engaging margins of the coupled panel and tower channel support 570. For example, the cable management access panel may snap into the tower support over bent tower channel support edge features 572 shown in FIGS. 26 and 27.

As can be seen in the exemplary embodiments disclosed in FIGS. 27 and 28, the improved storage management system may have an improved cable management system facilitated by cable apertures provided on the back or side of the tower support, as well as in various shelf aperture locations along the side and back walls of the shelves. In various embodiments, the improved cable management system may include a power distribution strip 519 provided inside the access panel of the tower support, as shown in FIG. 26. The power strip 519 may have auxiliary externally facing power distribution sockets 518 accessible to the outside through a rectangular or other shaped opening in the side wall near the top of the tower support 570, and an on/off and/or indicator switch 519 a accessible or visible through a switch/indicator aperture near the bottom of the side wall, as shown in FIGS. 23 and 27.

As shown in FIGS. 22-29, the illustrated and described exemplary embodiment of the improved storage management system is well-adapted to sit independently and securely on any horizontal support surface. Like the embodiments of the storage and management systems variously shown in FIGS. 1-16, the improved storage management system tower support may be quite tall, permitting the tower to be secure when set on a floor with mounting apertures 522 as shown in FIG. 29 for fastening by screws or other fasteners to a permanent structure such as a wall or other vertical support member. If there is a need for a tall storage management system to be located either semi-permanently or movably in a free-standing location, a support stand having a horizontally extending base with a support structure extending vertically from the base may be utilized. For example, a support stand having an optionally split base with plural base segments connected in spaced relation to provide a valley of sufficient width to receive the lower end of a tower support 510 may be utilized. Such plural base segments can be weighted or dimensioned in any suitable manner to provide vertical stability for the vertical support structure and a connected tall storage management system. Alternatively, such a base may have a continuous base segment, with the tower support seated directly thereon. In addition, the base may include appropriately sized support wheels and/or casters, as generally shown FIG. 16, to permit the support stand, with or without the attached storage management system, to be moved from place to place for convenient access or storage, as desired. Of course, when the connected storage management system is to be used for storage and charging of electronic devices it must be located with access to at least one suitable power outlet.

As shown in FIGS. 33, 35, and 36, an exemplary improved storage management system for electronic devices is also provided having a specialized coupling mechanism between the vertical channel support 570 and the base 515 to provide a secure connection and stability for the assembly. In various embodiments, this includes the use of fasteners produced by PEM® including PEM® nuts 512 and concealed head studs 513 for sheet metal as shown in FIG. 24. In addition, FIG. 24 reveals a plurality of resilient foot members 516 attached to the bottom of the base 515 to provide non-skid stability for the base on a support surface. It should be understood, however, that suitable alternative fastener methods and common fastener elements could be used instead and are contemplated within the scope of this disclosure. In addition, the embodiments shown in FIGS. 22-28 are shown as a metal assembly, however, it should be understood the assembly and components thereof may be crafted of various differing materials such as rigid extruded and/or vacuum-formed plastic, injection molded plastic, wood, or composites which are still within the scope of this disclosure.

FIGS. 29-31 a illustrate improved features of the storage and charging station system of the invention. FIG. 47 shows a top wall 551 of the charging system that is connected to the top ends of a pair of sidewalls 552 extending upwardly through locking slots 543 in the bottom portions 531 and adjacent edge portions 532 and 533 of the shelves 530. The top wall 551 has a downwardly extending rear flange 553 bolted to the front member of the vertical tower support, and a pair of opposed downwardly extending side flanges each bolted to one of the opposed side walls and adjacent edge portions of the top shelf. The top wall 551 structurally secures the assembly of the connected elements, including hinged locking door 554, and further secures the storage bay provided within the confines of the top shelf 530 by preventing unauthorized removal of an electronic device from the shelf so long as the security door remains closed and locked. Additionally the top wall may have one or more access holes 556, as shown, to help facilitate connection of the top wall flanges to the supporting structures, and also aid in the dissipation of heat from electronic devices being charged within the shelf storage bays below.

FIG. 30 illustrates improved shelves wherein an additional shelf edge cable management aperture 540 c is shown in the near edge portion of each of the illustrated shelves. The cable management aperture 540 c is located near the rear end of the edge portion, and is characterized by a cable management tab 541 which can be unitarily formed from the shelf edge portion to extend upwardly within the cable management aperture 540 c of the shelf edge portion 532. FIG. 31a illustrates an unnumbered shelf edge cable management aperture in the same near edge portion position as cable management aperture 540 c of FIG. 30, wherein the cable management aperture edges and the cable management tab of the unnumbered cable management aperture terminate at the upper margin of the shelf raised edge portion. FIG. 48 further shows an electronic cable 542 retained within the cable management shelf aperture 540 c by the cable management tab 541 to retain the cable adjacent the inside surface of the shelf near edge portion and adjacent side wall before extending outwardly from the storage bay through the shelf aperture 540 near the front end of the shelf edge portion 532 and around the front end of the shelf edge portion 532 to position the coupling end of the electronic cable within the margins of the shelf storage bay for easy electronic connection to an electronic device within the provided storage bay. The cable management tab 541 restricts lineal movement of the cable 542 through the cable management aperture 540 c sufficiently to linearly retain the cable at that location and accordingly control the length of the cable 542 during plugging and unplugging the cable coupling end to and from the associated electronic device stored in that shelf 530. It can be seen from that the referenced unnumbered cable management aperture of FIG. 31a , with edges and cable management tab terminating at the upper margin of the shelf raised edge portion, will facilitate providing an electronic cable through the said unnumbered cable management aperture in the same position as cable 542 is shown in cable management aperture 540 c of FIGS. 30 and 31.

FIG. 31 shows electronic cables 542 respectively emerging from cable apertures 520 in the side wall of the vertical tower support 110 and extending through back tab apertures 543 in the back tabs 533 of the shelf portions 530, which tabs are attached to the rear ends of adjacent shelf edge portions. The back tab apertures 543 direct the electronic cables to the shelf edge cable management apertures 540 c and associated cable management tabs 541, which in turn further retain the electronic cables in close proximity to the right angle corners of the shelves formed by the adjacent edge portions and back tab portions of the shelves. FIGS. 30 and 31 also show small cable tie holes 524 in the walls of channel 110 suitable for receiving cable ties to secure electronic cable in the channel 110 as desired.

In another exemplary embodiment of the assembly, FIG. 31a illustrates a modified sidewall 552 a having horizontal engagement slots 552 b in its outer edge 552 c. As shown in FIG. 31a , the modified sidewall 552 a extends down through locking slots 543 in the edge portions 532 and bottom portions 531 of shelves 530. The modified sidewall 552 a has been moved forward to cause the engagement slots 552 b to engage and provide vertical support for the bottom wall portion 531 of each of the shelves 530 of the array of shelves supported by a tower portion 510. Typically, but optionally, the top shelf 530 and the bottom shelf (not shown) of the shelf array will be bolted to the side wall 552 a through available holes in the side wall and shelf edge portions 532. The intermediate shelves 530 will be adequately supported by the engaged sidewall locking slots 543. The modified sidewalls with engagement slots 552 b can be sized to provide vertical support for any of the shelves with locking slots 543 coupled to any of the various tower supports disclosed herein.

The invention illustrated in FIGS. 32-43 and disclosed herein is generally directed to one or more embodiments of an improved mobile storage and charging station system for portable electronic devices. For ease of discussion and understanding, the following detailed description will at times refer to a “portable electronic device,” an “electronic device,” or a “plurality of electronic devices.” While certain Figures in the incorporated referenced provisional and non-provisional references illustrate an electronic device as a laptop computer, it should be appreciated that an electronic device may be any suitable portable electronic device requiring storage and/or battery charging or recharging. For example, an electronic device may include, but is not limited to, a laptop computer, a netbook computer, a notebook computer, a Google Chromebook™ computer, a tablet device (such as an Apple iPad®, Samsung Galaxy®, or Microsoft Surface®, or any similar known or future developed tablet), a mobile smartphone, or any other known or future developed mobile or portable electronic device.

Referring now to the Figures, FIGS. 32-37 illustrate one or more exemplary embodiments of an improved mobile storage and charging station assembly. FIG. 32 illustrates an improved mobile tower assembly 700, comprising a tower support 710 similar to tower support 110 of FIG. 1. Tower support 710 is coupled to an improved mobile base 770 in fixed relation to support the tower support 710 in a fixed vertical position when the lower plate 772 of the mobile base 770 is resting flat on a horizontal supporting surface such as a common building floor. A tower support frame 790 is likewise fixedly coupled to the rear sides of spaced tower support portions 714 and 715 and also fixedly coupled to spaced vertical connecting plate portions 776 of mobile base upper plate 774.

Referring to FIGS. 33-36, the lower and upper plates 772 and 774, respectively, of the exemplary mobile base 770, are advantageously formed of steel or other suitable metal, the front portions of which extend forwardly in substantially U-shaped fashion to provide a substantial footprint over a supporting surface, and a stable base and ballast for supporting the tower support and any structure supported by the tower. The U-shaped openings 778 and 779, respectively of the lower and upper plates of the base can be increased or decreased depending upon the relative weights of the base and tower and supported structure. Thus, increasing the design width and/or length of either or both of the U-shaped openings will increase the weight, ballast and forward balancing effect of the base, while reducing the design width and/or length of either or both of the openings will decrease the weight, ballast and balancing effect of the base, both with respect to stability of the tower assembly while stationary, and the balance and weight distribution of the mobile charging station tower assembly when the unit is pivoted rearwardly onto the rearwardly projecting wheels 780, as shown in FIG. 43, for balanced transport of the assembly in dolly-like fashion between points of storage, charging or use. The two rearward wheels 780 are supported by axle bolts 782 engaged in wheel hangar supports 781 formed by upwardly and rearwardly extending portions of the base lower plate 772. The wheels extend substantially to the same level as the base lower plate, which may include a pad (not shown) which covers the bottom surface of the lower plate 772 to substantially prevent the lower plate from marring a supporting surface.

The exemplary base upper plate 774 has forward portions which define each side of the upper plate U-shaped opening and are inclined downwardly from the level of the rear portion of the upper plate and terminate with short vertical legs 777 which are welded to the lower plate 772. The upper plate 774 additionally has a central downwardly extending support flange 775 which terminates on and is welded to the lower plate 772. The lower plate 772 additionally has an central upwardly extending tower support flange 773 which is closely spaced parallel to and rearwardly of the welded support flange 775 whereby the central member 711 of the exemplary aluminum tower support 710 may be secured closely between the steel support flanges 773 and 775 by bolts, machine screws and PEM® nuts, or any other suitable known or future-developed fasteners. Additionally, the base upper plate 774 has opposed cut-out openings 783 rearwardly of the downwardly extending support flange 775 and to either side of the upper plate opening from which the support flange 775 was cut and downwardly bent, which are positioned to closely receive the tower support portions 714 and 715, and the vertical frame members 792 of the tower support frame 790. Additionally, vertical connecting plate portions 776 are welded between the lower and upper base plates 772 and 774 immediately forward of the front edges of the cut-out openings 783. The exemplary vertical steel or aluminum frame members 792 and the tower support portions 714 and 715 are likewise secured to the connecting plate portions by bolts, screws and PEM® nuts, or any other suitable known or future developed fasteners. In addition, the tower support frame 790 includes a top frame portion 794 which extends between and connects the two vertical frame members 792 to provide a handle for supporting, pushing and controlling movement of the improved mobile tower assembly during transport of the tower assembly from venue to connected venue for storage, charging and convenient user access.

Accordingly, the tower support 710 is securely coupled to the connected support structure of the mobile base unit 770 and the vertical frame members 792 to provide an improved mobile tower assembly 700. Such mobile tower assembly 700, as shown in FIGS. 32 and 33, will securely support the plurality of shelf portions 730 and top wall 751 which are attachable to the central member 711 of the tower support 710, the first side wall 752 and second side wall 753 which are attachable to the plurality of shelf portions 730, the hinge members 755, doors 754, locking members (not shown) and locking handle or keyed lock 757 which are attachable to the side walls, and most importantly, the plurality of portable electronic devices (not shown) which will be individually placed in selected shelf portions 730 for charging, storage, withdrawal for use and return of the portable electronic members, during both stationary and mobile dolly-like use of the improved mobile tower assembly 700.

Referring now to FIG. 32, it is seen that the tower support 710 includes a first member 711, and second member 712 and third member 713 which are connected to the first member 711 to define a three-sided cable management channel 116. In addition, the tower support portions 114 and 115 are outwardly connected to the second member 712 and the third member 713, respectively. In different exemplary embodiments the various members and support portions may be perpendicularly connected as shown, or may be connected at acute or obtuse angles as the design may allow or require for function, appearance or ease of forming. The various members and portions of tower support may be formed of a unitary pressed, bent or molded material, although it should be appreciated that in one or more exemplary embodiments, the various members may be separately formed and coupled together. In the exemplary embodiment shown, the tower support 710 is advantageously and unitarily fabricated from bent aluminum sheet. Cable management channel 716 is utilized for the placement of one or more power strips and cable connectors (not shown) for providing power for charging each of the personal electronic devices individually positioned on each shelf portion as more extensively described in referenced U.S. Provisional Application 62/135,549. FIG. 37 shows a door 740 attached to a tower support vertical side member 792 by hinges 742 with one or more locks and/or handles 744 for securing and opening the door 740 to secure and access the power strip and cable connectors within the cable management channel 716. FIG. 37 also shows fasteners for coupling the vertical frame members 792 to the tower support 710 and the vertical connecting plate portions 776.

Because of the ease of identifying each portable electronic device with each user and each assigned storage shelf, and the speed and ease of user withdrawal for use and replacement for storage and charging of the portable electronic devices at multiple user sites, and the ability of teachers, supervisors, administrative staff and equipment managers to determine at a glance whether all personal electronic devices are out, or returned, the improved mobile storage and charging station of the invention saves enormous amounts of administrative time for the organization providing or managing the portable electronic devices.

Referring now more specifically to the exemplary embodiments of the present invention comprising an improved mobile multiple shelf tower assembly 800 for portable electronic devices illustrated in FIGS. 38-43, it is seen that the embodiments of FIGS. 38-43 differ in several respects from the previously described embodiments of FIGS. 32-37. FIGS. 38-43 illustrate an integral aluminum tower support 810 comprising a pair of side channels 814 and 815 extending outwardly, rearwardly and inwardly from the second and third members 812 and 813. Accordingly, in addition to the central cable management channel 816, tower support 810 provides two power strip channels 814 and 815, each of which houses a 12 outlet power strip 820 in the manner shown in FIG. 39, which is a section view taken along Section Line A-A on FIG. 40. Thus the tower support 810 is capable of providing power to portable electronic devices in 24 shelf portions 830, with side channel space and cable management channel space to accommodate the additional power strip and cable requirements for powering 24 portable electronic devices (not shown).

Additionally, tower support 810 optimally provides for attachment of up to 24 shelf portions 830 without significantly increasing the access height of the top shelf 830. The typical decrease in size of current personal electronic devices permits the use of shallower shelf portions 830 which may be more closely spaced to provide a single tower support for up to 24 shelves without exceeding a reasonable shelf height for users. However, increasing shelf density and numbers on a single tower support creates significant challenges with respect to power strip and cable connector management. These issues are solved by the improved tower support 810 with its added side channels for power strip placement and deeper central cable management channel 16 area. In addition, as shown in FIGS. 38 and 39, at least one and optimally two small cable tie holes 822 are provided in second channel member 812 and third channel member 813 adjacent each side of each vertically spaced shelf location on the tower support 810 to permit the optional use of common plastic cable ties (not shown) extending inside and outside the tower support 810 through selected and conveniently available cable tie holes 822 to retain cables running vertically and otherwise within the cable management channel 816 in close managed proximity to channel members 812 and 813. This provides for easier cable identification and service access to cables and cable access slots or holes 860 in the channel members 811, 812 and 813 and rear and side panels of shelf portions 830, in the manner shown in FIGS. 30 and 31 for the purpose of convenient user cable connection to and powering of the portable electronic devices for recharging each time a portable electronic device is reloaded into the shelf portions after every use. Such convenience is essential to minimizing reloading and connecting time when students or employees are required to re-shelve and charge all electronic devices at the end of a class hour or school or work day. Lack of convenience at that hectic time for the user can result in more class or work time loss to increase scheduled time for waiting to access replacement of 16 or 24 electronic devices in a single mobile tower assembly. In addition, if replacement and reconnection of devices at end of class hour or work period is inconvenient or difficult, many devices may be left unconnected and not recharged by frustrated users, requiring more monitoring by teachers or administrative managers.

The tower assembly shown in FIGS. 38-43 includes additional and improved security which is effective for the smallest of portable electronic devices. FIGS. 38 and 39 illustrate an improved sidewall 852 which extends for the entire length of the array of installed shelves 830 to substantially prevent any effective access to the shelf contents from either side of the array. The sidewalls 852 extend down both sides of the array of shelves 830, and within the margins of the shelf edge portions 832 through adjacent slots (not shown) in the shelf bottom portions 131. The exemplary sidewalls 852 are provided with at least one vertical open window 853 (two windows 853 are illustrated in FIGS. 38 and 39), window openings are defined by the surrounding margins of the sidewalls 852. The side walls 852 can be fastened to selected upper, mid-level and lower shelf edge portions 832 by machine screws and PEM® nut fasteners 858 or any other suitable known or to be discovered fasteners and are additionally retained in close proximity to the shelf edge portions 832 by slots in the shelf bottom portions 131 through which they extend. Effective side access to the interior of the shelves 830 and their contents is effectively prevented by the limited spaces between shelf edge portions 832 not covered by the sidewalls 852. Nevertheless, important visual access to the content of the shelves is importantly provided by the spaces between shelf edge portions 832 and the windows 853 to allow teachers or administrative personnel to quickly view the interiors of the shelves at any time to determine whether the electronic device assigned to any shelf is either present or absent, depending upon the time of day and the use, charging and storage/inventory requirements of the owner. As further best shown in FIG. 38, access to the contents of the upper shelf 830 of the shelf array is prevented by top wall 851 secured to the tower support in the same manner as more fully disclosed and referenced and incorporated above with reference to FIGS. 29-31. The top wall 851 is also beneficially attached to the top shelf 830 by suitable fasteners (not shown).

Access to the contents of the shelves is exemplarily controlled by door 854 and locking handle 857. The door is pivotally attached by hinges not shown and fasteners 855, which may be attached to sidewall 852, as shown, or other provided structure.

Access to the power strips 820 and cable connectors (not shown) is provided by rear door 840, as shown in FIG. 40. Door 840 is pivotally attached by hinges 842 to the back side of power strip channel 814 of the tower support 810, with one or more locks and/or handles 844 for securing and opening the door to secure and access the power strips 820, cable connectors (not shown) and cable access slots or holes 860 in the tower support to reach the shelves within which the portable electronic devices must be connected.

The tower support 810 has an attached top wall 851 defining ventilation openings 856, as shown in FIG. 38. Likewise, rear door 840 has ventilation openings 844 shown in FIG. 40. The ventilation openings 844 and 856 allow cooling air to enter the lower ventilator openings 844 and flow upwardly through the tower support 810 whereby air within the tower support which is heated by the operation and electrical conduction by the power strips 820 and cable connectors (not shown) will pass out of the tower channel through the top wall ventilation openings 856.

The exemplary mobile base 870 which is illustrated is FIGS. 38-43 for use with the improved mobile storage and charging station assembly 800 is essentially the same as the mobile base 770 illustrated in FIGS. 32-37, except for changes made possible by the one-piece design of the improved tower support 810. The increased stiffness of the tower support 810 provided by side channels 814 and 815 enabled the elimination of both the structure and the weight of the tower support frame 710 of the embodiment of FIGS. 32-37. Thus it is not necessary to provide the spaced vertical connecting plate portions 776, which function to connect the vertical frame members 792 to the base 770, nor is it desirable to provide the two upper plate cut-out openings 783 in the mobile base 870. It will be seen from FIG. 38 that the side channel 814 of the tower support 810 does not extend below the top surface of the upper plate 874 of the mobile base 870. The tower support middle channel member 811 is connected to the lower plate central support flange 873 and the upper plate central support flange 875 in the same manner as previously described with respect to tower support middle member 711 and support flanges 773 and 775 and as shown in FIGS. 32-38. In all other respects, the mobile base 870 is substantially the same as mobile base 770.

The improved mobile storage and charging station assemblies 700 and 800 both include a combination of components which combine to efficiently and securely store, charge and conveniently move to convenient user venues multiple portable electronic devices for classroom and conference room use and user training, and further permit fast and easy user dispensing, and return of charging connection of assigned electronic devices by the users, with little supervision by teachers or administrative personnel. The novel mobile base designs illustrated and described herein have an open design which permits interior access for fabrication and rigid connection of tower supports, but also permits design adjustments to provide more or less weight depending upon the number of shelves attachable to the tower support and the type of portable electronic devices targeted for storage and charging. The base and attached tower support provide stability when the assembly is stationary, and balance and ease of transport of contents in well-balanced dolly-like manner when it is desired to move the mobile storage and charging station assembly between storage, charging and convenient use venues within a facility. While exemplary embodiments of the present invention have been illustrated and described, it should be clear that various design changes, substitution and selection of available and advantageous materials, and aesthetic or use oriented changes can be made to the structure and arrangement or inclusion of features described herein or in U.S. Provisional Application 62/135,549, the subject matter of which is incorporated herein by reference, without departing from the objects of the invention.

Assemblies 100, 200, 300, 400, 500, 600 and other improved embodiments shown also include certain advantages that may not be readily ascertainable from the disclosure provided herein. The assembly provides a simple, clean, easy to use space saving design for the effective management of portable electronic devices. The sloped sides of the edge portions of each shelf portion provides an open design which provides easy viewing of electronic devices stored therein. The easy viewing allows for ease of inventory and management of electronic devices. The cable management system provided with the associated channel avoids an undesired mess of inter-tangled cables, while also protecting cables from damage or loss since the cables generally do not need to be removed. The vertical stacking of the plurality of shelf portions provides for a low profile and small footprint, providing space savings. For example, in a school setting, by incorporating the vertical stacking arrangement, the assembly has a footprint similar to a school locker while able to store and manage a full classroom of electronic devices. The locking assembly provides a door having no pinch points, which can avoid damage to cables or users. In addition, by providing a central battery charging and/or recharging location for all portable electronic devices stored in assembly, the risk of loss of battery charging devices is greatly reduced. Since the battery charger, AC adapter(s), or other charging device remains with the assembly when the portable electronic devices are removed, there is a reduced chance of theft or loss of the battery charging device.

In addition, updating or performing a central data transfer to portable electronic devices stored in assembly is made easier. For example, a party performing the update may plug in or hook up a data cable, such as a CAT5 or CAT6 cable, to each device in assembly. As an alternative, each device may be connected to a central data hub while being stored in the assembly, allowing for a distribution of updates through the central data hub. Such a connection may be wired or wireless. In either case, the party performing the update may quickly and easily update portable electronic devices stored in the assembly, as portable electronic devices are centrally located and accessible while being stored. The assembly also allows for users to manage pick up and drop off of portable electronic devices. This is especially advantageous for applications in primary schools, where users may be children, and more specifically young children. In this application, portable electronic devices can be easily picked up and dropped off by children without substantial supervision by an adult or teacher. For such classroom use, the assembly illustrated and described herein facilitate complete management of the removal/unplugging and return/plugging in of electronic devices by the student with only the unlocking and locking of the door requiring action by the teacher. In a typical school year cycle, the assembly can save in excess of 60 hours of classroom time for the teacher, which may otherwise be used for classroom instruction, as compared to a classroom where the electronic devices are accessed from and returned for charging to a typical cart by the teacher.

The assemblies disclosed in FIGS. 22-43 also include certain advantages that may not be readily ascertainable from the disclosure provided herein. The improved shelf mechanisms shown therein allow for adult and child users to reach into the assembly, grip both top and bottom surfaces of and retrieve an electronic device easily from any angle. Because a user may be standing, crouching, leaning, or in any other position while removing the device, it is important the user should have a firm grip on the device to prevent damage and injury. Likewise, the user can maintain a firm grip on the device while correctly positioning the device on a shelf for storage and charging.

The improved cable management system allows for protection of the power distribution strips. Removable access panels cover the power distribution elements, while the cable management system provides connectability by the user for charging, while limiting possible interaction with electricity by the user and preventing shock or injury. It also limits movement of the power strip and charging components, which can prevent the device charging components from damage caused by repeated removal.

The metal structure, specialized fasteners, and floor/supplemental mounting features all provide for a secure storage system. This is especially important as the number of devices grows and the tower is taller. The system may be deployed in classrooms, where users may bump into the tower without likely damage to its components or the stored electronic devices. These improved features allow the system to support a large number of devices without compromising safety and stability.

Referring now more specifically to the exemplary embodiments of the improved mobile multiple shelf tower assembly 900 for portable electronic devices illustrated in FIGS. 44-59 b, it is seen that the embodiments of FIGS. 44-59 b differ in several respects from the previously described embodiments of FIGS. 8-12 and 29-32. In FIG. 44 it can be seen that the bottom portions 931 of shelves 930 each have a protruding rear support shelf 936 which extends rearwardly through shelf alignment support slot 919 in tower first support member 911 to provide a support surface for a power “brick” 939 (as shown on the second from the top rear support shelf 936 in FIG. 44) to be provided for powering an electronic device placed upon the shelf bottom portion 931 from which the rear support shelf 936 protrudes. As more fully shown in FIG. 48a , each rear support shelf 936 may advantageously have a plurality of holes 936 a and/or slots 936 b to conveniently accommodate strap materials such as cable zip ties (not shown) or other suitable linear tie materials for fixedly retaining the power brick 939 on the shelf during its use. The margins of alignment support slot 919 provide additional vertical support for the shelf 930, as well as the protruding rear support shelf 936 and a power brick 939.

As shown more particularly in FIGS. 44-59 b, the improved storage and charging system 900 includes a vertical tower assembly 910 which can advantageously be fabricated from one piece of material to include a vertically extending first support member 911, which may be attached to opposed second support member 912 and third support member 913 to form a channel 916, and may have a top wall 951 a extending rearwardly at a right angle from the first support member and preferably welded at its side edges to the top edges of the second support member 912 and the third support member 913, respectively, and engagement tabs 914 and 915 respectively extending outwardly from the rear edges of the second support member 912 and second support member 913 to facilitate attachment to a vertical wall (not shown), a vertical frame, such as frame 990 shown in FIGS. 50-52 and 55-56, or any other suitable vertical structures. A plurality of shelves 930 may be coupled to the first support member 911, as previously described, in a stacked vertical array. The shelves 930 may each have a bottom portion 931, a first edge portion 932, and a second edge portion 933. The edge portions may each have a first back tab 914 and a second back tab 915 respectively formed from portions of the first edge portion 932 and second edge portion 933, and extend therefrom at approximately right angles to abut the first support member 911. A retaining hook 937 extends rearwardly from the end of each of the backtabs to engage a shelf receiving slot 919 a of first support member 911 and includes a hook portion 937 a which engages the outer side margin of the receiving slot 919 a to retain the shelves on the support member 911. The exemplary edge portions 932 and 933 each will flex from the vertical to enable the retaining hooks 937 to pass through the receiving slots 919 a, but have a vertical bias with respect to the bottom portion 931 to cause the retaining hooks 937 to move outwardly and the hook portions 937 a to engage and remain engaged with the outer margins of the first support member 911. As previously indicated, the protruding rear support shelves 936 of the flow-through shelf bottom portions 931 extend through and are supported by the lower margins of the shelf alignment support slots 919 of first support member 911.

FIGS. 44-48 a further illustrate a locking assembly 950 of the tower assembly 900. The locking assembly 950 includes a pair of opposed first and second side walls 952 and 953, respectively coupled to a top wall 951 which is positioned above the top-most shelf 930 of the tower assembly. At least one and normally both of the sidewalls are coupled to at least one shelf 930 of the array of shelves, and locking assembly side walls 952 and 953 extend downward on opposite sides of and adjacent to each shelf to obstruct user side access to the storage bay defined by the bottom portion 931, edge portions 932 and 933, and first and second back tabs 934 and 935 of each shelf 930. As shown, each shelf 930 advantageously may include a first locking slot 933 a provided at the intersection of the first edge portion 932 and bottom portion 931 and a second locking slot 933 b provided at the intersection of the second edge portion 933 and the bottom portion 931, which locking slots are of greater length than the width of the first and second sidewalls, and of greater width than the thickness of the sidewalls to permit each of the adjacent sidewalls to extend vertically through the aligned slots of the adjacent shelves. The adjacent sidewalls 952 and 953 each advantageously may have a plurality of horizontal engagement slots 952 a and 953 a, respectively, spaced along a sidewall outer edge at the same intervals as the plurality of shelves 930 are coupled to the tower support 910, whereby the sidewalls can be shifted horizontally to cause the shelves to each be retained within the horizontal engagement slots to thereby provide vertical support for the shelves in the same manner as the tower assembly of FIG. 31a , more specifically shown and described above.

The locking assembly 950 of the tower assembly 900 of FIGS. 44-59 b additionally includes a door 954 attached by hinges 955 to sidewall 953, which door extends partially across the open ends of the array of shelves 930, as shown in FIG. 45, to prevent physical access to electronic devices (not shown) placed on the shelves when the door is closed and locked by lock assembly 957 partially shown on the outer face of the door 954, and permit access to and removal of the electronic devices from the assembly 900 when the door is unlocked and swung open. The locking mechanism is partially mounted on shelf 930 a as shown in FIG. 47. As previously shown in other tower assemblies described herein, the partial coverage by the door 954 of the interior of the assembly, and the illustrated incline of the shelf edge portions 932 permits the staff of the facility in which the tower assembly 900 is placed to determine by view from a distance which shelves support electronic devices for storage and charging, and which shelves do not, as best illustrated by FIG. 46. Thus it can be determined if any electronic devices are missing at any time without requiring opening of the door.

FIG. 45 also shows shelf apertures 941 in the back tabs 934 of shelves 930, which align with tower support cable apertures 120, best shown in FIG. 49a . As shown in the drawings, both back tabs 934 and 935 may advantageously include shelf apertures 941 to register with provided tower support cable apertures 920 to provide more convenient electronic cable supply options for the electronic devices to be placed on the shelves 930.

FIG. 47 reveals a power distribution strip 917 attached to the second support member 913 of the tower support 910 to provide a plurality of electrical outlets 918, each of which is located adjacent to the space above a shelf bottom portion rear protrusion 936 to conveniently supply electrical power to a power brick 939 provided on the rear protrusion 936 as shown. The conventional power cord (not shown) can be conveniently bundled and secured on the rear protrusion 936 of the shelf bottom using conventional zip ties secured to a slot 936 b in the rear protrusion 936 shown in FIG. 46a . FIG. 47 also clearly shows cable management apertures 940 near the front distal ends of the tapered second edge portions 233 of shelves 230, as well as double cable management apertures 940 a near the rear ends of the second edge portions 233 to conveniently provide a controlled length of electronic cable to electronic devices placed on each of the shelf bottom surfaces 931 for charging, as previously described with respect to the countertop assemblies of FIGS. 30-31 a. The drawings show such cable management apertures 940 and double cable management apertures 940 a provided in each of the first and second edge portions 232 and 233 for added convenience.

The drawings also show main power supply cable apertures 923 located at the lower ends of the second support member 912 and third support member 913 to conveniently receive the main power supply cord 917 a of power distribution strip 917. The abbreviated main power supply cord 917 a, which can be quite long with a conventional grounded electrical plug end (not shown) to engage a common facility electrical outlet (not shown), is shown extending from the lower end of the power distribution strip 917 in FIG. 47 in close proximity to cable apertures 923, which may conveniently be provided on both the second and third support members to accommodate the location of the nearest power outlet to the position of the tower support 910. As shown in FIG. 45, a pair of spaced J-hooks 917 b may be provided on the middle and lower portions of either support member 913 (as shown) or 912 to provide cord retaining structure about which to wrap such length of the power supply cord as is not entirely extended to a distant electrical outlet. As shown in the exploded isometric drawing of FIG. 49b , showing the “upright” J-hook in position for attachment, the J-hook 917 b is attached to the third support member 913 by a bolt 917 c and associated washer 917 d and cap nut 917 e, or other suitable fastener hardware. It can be seen that the J-hook 917 b defines a rear cavity between the sidewalls of the shank of the J-hook. A push-out tab 913 a is shown formed in the third support member 913 to extend between the sidewalls of the fastened J-hook 917 b to prevent the J-hook from rotating around the bolt 917 c from its normal upright vertical position on the middle portion of support member 913. It can be seen from FIG. 45 that the lower J-hook 917 b is identical to the previously described middle J-hook 917 b, except that it is fastened to the support member directly below the middle J-hook 917 b in an inverted position in the same manner with similar fastener hardware as middle J-hook 917 b, and in registry with a similar third support member push-out tab 913 a (not shown) to prevent its rotation about the fastener bolt 917 c. Thus, between uses the power supply cord 917 a may be wrapped around the pair of J-hooks 917 b in a convenient manner for efficient storage.

As previously indicated, FIG. 50 shows the improved storage and charging system tower assembly 900, mounted on a rectangular steel square tube vertical support rear frame 990, which in turn is attached to a stationary base stand 970. The square tube vertical support frame may be fabricated from 1.5 inch by 1.5 inch 16 gauge square steel tube length shown in FIG. 54. As illustrated, the front, left and right sides of the tube have been notched in three places for bending, and tapered at the ends, at substantially 45 degree angles to permit the right side of the tube to be bent at the notches into a rectangular frame with three corners formed by the mating notches, and with the tapered ends joined to form a fourth corner. The corners and end mating surfaces of the bent tube are welded to form the closed rectangular frame of FIG. 53. The front surfaces of the two vertical sides 992 of rear frame 990 are each machined to receive three hex rivet nuts 992 a, as shown, to respectively receive common fastener bolts 992 b to attach the first and second channel engagement tabs 914 and 915.

Whether supported on the stationary base 970 of FIGS. 50-52, or the mobile base 975 of FIGS. 55-57, the rear frame 990 is beneficially provided with a lockable rear door 980, as shown in FIGS. 51 and 56. An exemplary door 980 is formed from 0.060 flat steel material and is planar except for two door stops 981 which extend from the distal side edge 980 a of the door 980 and are exemplarily bent rearward and then back parallel to the plane of the door, as best illustrated by enlarged detail FIG. 58b , to provide about a one-quarter inch offset between the inside plane of the door 980 and the inside plane of the door stops 981 to allow the outer margins of the closed door to fit within the interior of the rear frame 990. The door is pivotally hung on the rear frame 990 by two side hangars 982 which extend from the engaged side edge 980 b of the door 980 in the plane of the door. The side hangars 982 extend outwardly and downward from the side 980 b of the door 980 to each define a downwardly opening slot 983 between the finger-like lower extension of the side hanger 982 and the opposed connected side edge 980 b of the steel door. The rear frame 990 on which the door 980 is hung has a pair of door receiving slots 994 of approximately 0.160 inch width and sufficient length to receive the side hangers 982 of the steel door. The upper ends of the slots 994 of the frame 990 and the depth of the mating supporting surfaces of side hanger slots 983 are such that the rear door 980 is supported within the confines of the rear frame 990 in close fitting relation to prevent access to the structure and components within the channel 916 attached to the frame 990 when the rear door 980 is closed. As previously noted, the door stops 981 on the distal edge of the door 980 will be engaged against the rear surface of the adjacent vertical side 992 of the rear frame 990 when the rear door is in its closed position, wherein it can be retained in such closed position by rear door lock 985, the latch of which is engageable within frame latch receiving slot 995. The unnumbered apertures shown in the side hangers 982 are non-functional hang holes for transporting the door during fabrication, and are not necessary features of the invention. Four ventilation openings 986 are exemplarily provided in the lower portion of the door 980 which cooperate with openings in the top wall 951 a of the tower assembly 900 to provide updraft ventilation and cooling for electrical components which may be supported within the channel 916 on the shelf bottom portion rear protrusion 936.

As further shown in FIG. 50, the stationary base 970 comprises a right support member 971 and a left support member 972. Base support members 971 and 972 are preferably fabricated of steel for reasons of weight stability and cost, and each are attached by bolts 970 a to the lower two hex rivet nuts 993 a positioned and attached to the outside lower surfaces of vertical sides 992 and 993 of the rear frame 990, as shown in FIGS. 50-52. The stationary base support members 971 and 972 may each extend rearwardly and outwardly, and forwardly and outwardly, from their points of attachment to the rear frame 990, as shown in FIGS. 50-52, to provide a stable support for the rear frame 990 and the attached storage and charging system 900 and any supported electronic devices and electrical cable accessories thereon. In addition, the distal ends of the support members 971 and 972 may be equipped with support pads 973 to provide a support structure of ample length and breadth for the stationary base 970 and all supported structure and apparatus.

In another exemplary embodiment, FIGS. 55-57 illustrate a mobile base 975 attached to the rear frame 990. The steel mobile base is attached by bolts 975 a to the lowest and highest of the three hex rivet nuts 993 a attached to the outside lower surfaces of vertical sides 992 and 993 of the frame 990. The mobile base 975 includes a right support member 976 and a left support member 977 which may each extend rearwardly, forwardly and outwardly from their points of attachment to the frame 990. The forward and rearward portions of the support members 976 and 977 are equipped with rear wheels 978 rotatably provided on axles extending outwardly from the support members parallel to and at some distance behind the rear frame 990, as exemplarily shown in the drawings. The forwardly and outwardly ends of the support members 976 and 977 are equipped with dolly wheels 979, which are both pivotable about vertical axes and rotatable about horizontal, as shown in FIGS. 55-57, to provide stable, steerable support mobile support for the supported structure and any apparatus thereon. The dolly wheels 979 b may each include a conventional lockable foot-operated brake 979 b, which may be a wheel brake or a total wheel and pivot brake, to provide a more stationary support when the brake(s) is locked. A connecting strut 979 a extends between the right and left support members 976 and 977 to provide lateral stability for the forward ends of the mobile base 975. It can be seen that the strut 977 a extends well below the lowermost shelf 930, which is supported with the other shelves in cantilever manner by the channel 916 and the attached rear frame 990, which in turn is supported by the mobile base 975 in a mobile manner.
